Analysis of the Adequacy of the Placement of Advanced Medical Devices in the Conceptual Area utilizing Open Data and the Center of Population

Abstract

　Since the medical plan is promoting the clarification of medical institutions that are responsible for outpatient services to utilize medical resources, we analyzed the appropriateness of the placement of advanced medical devices in the conceptual area by using open data and the population center of gravity. The distribution of advanced medical devices in the conceptual area was grasped by center-of-gravity analysis using the number of installed advanced medical devices and the number of tests performed by each medical institution in the functional reporting of hospital beds and the medical function information provision system, and a comparative analysis of the distance and direction between the treatment rate and the center of gravity of the population receiving treatment based on population distribution was conducted. The distribution of advanced medical devices and the number of tests per device did not correspond to the center of gravity of the population receiving care. In addition to this, it was found that by conducting simulations in which the number of tests and locations of advanced medical equipment are varied, the optimal layout for the region can be obtained, and this should be used to promote the installation and renewal of equipment in the entire region.
